The mechanism by which molecular oxygen is activated by the organic cofactor pyridoxal phosphate (PLP) for oxidation reactions remains poorly understood. Recent work has identified arginine oxidases that catalyze desaturation or hydroxylation reactions. Here, we investigate a desaturase from the Pseudoalteromonas luteoviolacea indolmycin pathway. Our work, combining X-ray crystallographic, biochem
Action spectra are important biological weighting functions for risk/benefit analyses of ultraviolet (UV) radiation (UVR) exposure. One important human benefit of exposure to terrestrial solar UVB radiation (∼295 to 315 nm) is the cutaneous synthesis of vitamin D3 that is initiated by the photoconversion of 7-dehydrocholesterol to previtamin D3. An…
In landscapes that support economic and cultural activities, human communities actively manage environments and environmental change at a variety of spatial scales that complicate the effects of continental-scale climate. Here, we demonstrate how hydrological conditions were modified by humans against the backdrop of Holocene climate change in southwestern Amazonia. Paleoecological…
Islands are useful model systems for examining human–environmental interactions. While many anthropogenic effects visible in the archaeological and paleoecological records are terrestrial in nature (e.g., clearance of tropical forests for agriculture and settlement; introduction of nonnative flora and fauna), native peoples also relied heavily on marine environments for their subsistence…
Southern China and Southeast Asia witnessed some of their most significant economic and social changes relevant to human land use during the Late Holocene, including the intensification and spread of rice agriculture. Despite rice growth being associated with a number of earth systems impacts, how these changes transformed tropical vegetation…
Large, low-density settlements of the tropical world disintegrated during the first and second millennia of the CE. This phenomenon, which occurred in South Asia, Southeast Asia, and Mesoamerica, is strongly associated with climate variability and extensive landscape transformation. These profound social transformations in the tropical world have been popularized as…
This paper addresses an important debate in Amazonian studies; namely, the scale, intensity, and nature of human modification of the forests in prehistory. Phytolith and charcoal analysis of terrestrial soils underneath mature tierra firme (nonflooded, nonriverine) forests in the remote Medio Putumayo-Algodón watersheds, northeastern Peru, provide a vegetation and fire…
The extinction of iconic species such as the dodo and the deforestation of Easter Island are emblematic of the transformative impact of human colonization of many oceanic islands, especially those in the tropics and subtropics. Yet, the interaction of prehistoric and colonial-era colonists with the forests and forest resources they…
The impacts of human-induced environmental change that characterize the Anthropocene are not felt equally across the globe. In the tropics, the potential for the sudden collapse of ecosystems in response to multiple interacting pressures has been of increasing concern in ecological and conservation research. The tropical ecosystems of Papua New…
The environmental crises currently gripping the Earth have been codified in a new proposed geological epoch: the Anthropocene. This epoch, according to the Anthropocene Working Group, began in the mid-20th century and reflects the "great acceleration" that began with industrialization in Europe [J. Zalasiewicz et al., Anthropocene 19, 55–60 (2017)]….
Iron (Fe) is an essential micronutrient whose availability is limiting in many soils. During Fe deficiency, plants alter the expression of many genes to increase Fe uptake, distribution, and utilization. In a genetic screen for suppressors of Fe sensitivity in the E3 ligase mutant bts-3, we isolated an allele of…
Why are women socially excluded in fields dominated by men? Beyond the barriers associated with any minority group's mere numerical underrepresentation, we theorized that gender stereotypes exacerbate the social exclusion of women in science, technology, engineering, and math (STEM) workplaces, with career consequences. Although widely discussed, clear evidence of these…
How early human foragers impacted insular forests is a topic with implications across multiple disciplines, including resource management. Paradoxically, terminal Pleistocene and Early Holocene impacts of foraging communities have been characterized as both extreme—as in debates over human-driven faunal extinctions—and minimal compared to later landscape transformations by farmers and herders….
African savannas are the last stronghold of diverse large-mammal communities, and a major focus of savanna ecology is to understand how these animals affect the relative abundance of trees and grasses. However, savannas support diverse plant life-forms, and human-induced changes in large-herbivore assemblages—declining wildlife populations and their displacement by livestock—may…
For some teenagers, the new school year means reuniting with their friends. For others, it means an increase in anxiety and in the pressure to succeed and get good grades. According to researchers at the University of Ottawa, this can lead to perfectionism and, in turn, to anxiety and depression.
Multitude of conspiracy theories people believe in all over the world is astonishing. They actually accompany each significant event: a catastrophe, assassination, death of a famous person or, currently, the COVID-19 pandemic. Because the formation of a distorted image of reality is so widespread this topic has been dealt with by numerous scientists. Various studies, articles and books using psych

Crypto is absolutely lousy with memes: meme stocks, memes about stocks, and, inevitably, stonks. You've probably heard of Dogecoin by now, unless you have been off-world for several years (and in that case, how was the weather?). Based on the wildly popular shiba inu meme, business shibe is the mascot of Dogecoin, perhaps the best known of the B-list cryptocurrencies. But now, there is a living,
A new methodology for quantifying landscape changes on barrier islands shows storms that can devastate human infrastructure also create opportunities for coastal wildlife to thrive. "Our goal for this project was to develop a method to quantify land cover changes from natural processes and storms on barrier islands," says Beth Sciaudone, a research assistant professor of civil, construction, and
A little more sexy time for symbionts could help coral reefs survive the trials of climate change, researchers report. And that, in turn, could help us all. Researchers already knew the importance of algae known as dinoflagellates to the health of coral as the oceans warm, and have now confirmed the tiny creatures not only multiply by splitting in half, but can also reproduce through sex. "Most s
Nature, Published online: 28 September 2021; doi:10.1038/d41586-021-02612-5 Concrete will be crucial for much-needed climate-resilient construction. But the cement industry must set out its plan for decarbonization.
When you work, you expect to be paid for it. Except, for millions of Americans employed across a range of industries like restaurants and construction, that's not always the case. Anthropologist Rebecca Galemba explores the multibillion-dollar problem of wage theft and how employers get away with it, highlighting the changes needed for them to pay up — and fairly.
Research by Wageningen Bioveterinary Research (WBVR) has shown that the risk of airborne transmission of high pathogenic avian influenza virus from infected wild birds is negligible. The research looked specifically at the airborne movement of particles from wild waterfowl droppings in the vicinity of poultry farms during the risk season for avian influenza (October to March). It also considered t
Researchers at the Paul Scherrer Institute PSI are the first to have joined two proteins together by means of a free-standing, rigid link. The structural element holds the two protein molecules together at a defined distance and angle, much the way a barbell handle connects two weights. This type of linkage could help, for example, to develop so-called virus-like particles for vaccines. The resear
Researchers have developed a methodology for quantifying landscape changes on barrier islands and, in doing so, have found the storms that can devastate human infrastructure also create opportunities for coastal wildlife to thrive.
Why did some ancient Khmer and Mesoamerican cities collapse between 900-1500CE, while their rural surrounds continued to prosper? Intentional adaptation to climate changed conditions may be the answer, suggests a new study.
Geologists completed research characterizing the complex geological evolution of the Orphan Basin, offshore Newfoundland and Labrador, using an extensive database of newly available, modern 2D and 3D broadband seismic reflection data.

Classic antidepressants could help improve modern cancer treatments. They slowed the growth of pancreatic and colon cancers in mice, and when combined with immunotherapy, they even stopped the cancer growth long-term. In some cases the tumors disappeared completely, researchers have found. Their findings will now be tested in human clinical trials.
In the Middle Bronze Age (about 3600 years ago or roughly 1650 BCE), the city of Tall el-Hammam was ascendant. Located on high ground in the southern Jordan Valley, northeast of the Dead Sea, the settlement in its time had become the largest continuously occupied Bronze Age city in the southern Levant, having hosted early civilization for a few thousand years. At that time, it was 10 times larger

Living or biological systems cannot be easily understood using the standard laws of physics, such as thermodynamics, as scientists would for gases, liquids or solids. Living systems are active, demonstrating fascinating properties such as adapting to their environment or repairing themselves. Exploring the questions posed by living systems using computer simulations, researchers at the University
Tropical rainforests are the most biodiverse habitats on Earth. They are home to a huge number of different plants, animals, fungi and other organisms. These forests are primarily spread over three continents, concentrated in the Amazon Basin in South America, the Congo Basin in Central Africa, and the vast archipelago of Southeast Asia.
In a crisis, women make significantly longer phone calls and adhere more closely to governmental measures than men; men are less willing to have their mobility restricted and return to normal more quickly than women. Researchers at the Complexity Science Hub Vienna (CSH) found cliché-sounding behavioral patterns like these in data from the first coronavirus lockdown in spring 2020.
When you become very good at one thing, that sometimes comes at the expense of something else. Such trade-offs also apply to bacteria. When becoming more resistant to one antibiotic, bacteria can sometimes become more sensitive to another. Linda Aulin, Ph.D. candidate in the pharmacology group of Coen van Hasselt now try to figure out how we can use this phenomenon to combat the emergence of antib
Globally only about 20% of waste plastics are recycled. Boosting that figure remains a challenge as recycling plastic cleanly can be expensive and usually produces lower-value products, often making it financially unviable.

Because of financial barriers for clinical interventions, intensive educational interventions in school settings often are the primary resource for children with autism from lower-income families. Continuity of care in school settings can require coordination, referred to as social capital, between the "team-around-the-child" (TAC) – the parents, school staff and community providers. However, ineq
"One thing that can get lost in digital teaching is the process of building social relationships. This network building normally takes place during coffee breaks, shared lunch and in the queue at the toilet or coffee machine," says Gunhild Marie Roald, an associate professor in NTNU's Department of Education and Lifelong Learning.
Researchers from Chalmers University of Technology, Sweden, have succeeded in creating tiny vehicles powered by nothing but light. By layering an optical metasurface onto a microscopic particle, and then using a light source to control it, they succeeded in moving the tiny vehicles in a variety of complex and precise ways—and even using them to transport other objects.
At the end of the 1970s, infanticide became a flashpoint in animal behavioral science. Sociobiologist Sarah Hrdy, then a Harvard Ph.D. student, shared her observation in her published thesis that whenever a new langur male entered an established colony, infants would either begin to disappear or show evidence of wounds. Hrdy concluded this was done to eliminate the progeny of rivals and free up no

Ensuring a steady food supply is a problem in many regions of Africa—and the strong population growth will only exacerbate it in the future. Yet the agricultural sector could definitely produce greater yields. Experts estimate that current harvests are 20 to 60 percent lower than they could be.
Over two days in the summer of 1910, wildfires roared across the bone-dry forests of the inland Northwestern U.S., the Rockies, and parts of British Columbia. Whole towns burned. The blazes scorched 3 million acres of forest, an area the size of Connecticut, and left behind a legacy that profoundly changed how the U.S. managed wildfires—and ultimately how fires behave today.
How should we relate to the traditional historiography on ancient Sicily? The prevailing view has been that the indigenous population had neither territory, power nor economic resources. But with the aid of interdisciplinary methods, a new thesis shows that trade was a big part of the economy for the inhabitants of the settlement of Monte Polizzo.
Reporters looking for insight and research around the phenomena of "missing white woman syndrome," please see comments from Syracuse University professor of communications Carol Liebler of the Newhouse School.
Older people are just as likely as younger people to recognize the need for action on climate change and to say they're willing to make big sacrifices to protect the environment, suggesting claims of a generational divide over the future of the planet may be exaggerated, according to a new UK study marking the publication of the book Generations by Professor Bobby Duffy.
New research from Flinders University has uncovered further details on how the guinea pig gut forms solid fecal pellets, providing potential insights that could help in the management of human bowel issues.

Ice melange, a slushy mixture of snow and ice chunks, can heal large rifts in Antarctica's ice shelves. Researchers found that a thinning of ice melange may have enabled a Delaware-sized iceberg to break off from the Larsen C ice shelf in 2017. A new article has the scientists' analysis of the dynamics behind large iceberg calving events.
Researchers suggest that advances in breast cancer prevention research have resulted in new and innovative opportunities to modify breast cancer risk and potentially reduce breast cancer incidence and mortality.
In many North American lakes, a tiny clawed creature has become a big bully. The invasive rusty crayfish roams lakebeds, snapping up snails, bivalves, and water plants, cutting off food supplies for native crayfish and other animals. And when they're feeling saucy, some mount daring raids on fish eggs, reducing sport-fish populations.
Although female giraffes have closer 'friends' than male giraffes, male giraffes have more 'acquaintances' than females, according to new research. The study demonstrates that giraffes form a complex multilevel society that is driven by differences in the social connections among individuals, which could have conservation implications for the endangered giraffes.
The missing link isn't a not-yet-discovered fossil, after all. It's a tiny, self-replicating globule called a coacervate droplet, developed by researchers to represent the evolution of chemistry into biology.
The U.S. is seeing an increased use of cannabis resulting from its legalization for recreational purposes. The findings showed that passage of the laws led to a rise in the odds of past-year and past-month cannabis use among individuals of Hispanic, Other and non-Hispanic whites compared to the period prior to enacting laws for recreational use. However, legalization did not lead to use more frequ
Nature, Published online: 27 September 2021; doi:10.1038/d41586-021-02647-8 Those who give scientific- and academic-career advice should be wary of survivorship bias. Plus, junior naturalists discover an ancient giant penguin, and why the world must work with Kabul on immunizations.
Scientists believe that the first beings we could call modern humans emerged in Africa some 300,000 years ago. Over the millennia, Homo sapiens expanded across the world but didn't reach North America until around 13,000 years ago, or that used to be the prevailing wisdom. A discovery of preserved human footprints in White Sands National Park in New Mexico has pushed that timeline back by thousan
The current estimate is that the average human brain contains 86 billion neurons. These neurons connect to each other in a complex network, involving 100 trillion connections. The job of neuroscientists is to map all these connections and to see how they work – no small task. There are multiple ways to approach this task. At first neuroscientists just looked at the brain and described its macrosc
Whether atomic priesthoods, 50ft concrete spikes or burying astronauts in concrete, humanity's attempts to keep free from infection are examined in Until Proven Safe In January 2020, just a few days before the first Covid-19-infected passengers landed in the United States on a flight from Wuhan, preparations were already being made in a converted car park in Omaha, Nebraska. By complete coinciden
Many asylum seekers and refugees have had to flee their homes in extremely distressing circumstances. A lucky few make it to a safe country such as the UK – but what happens next? As Britain begins its commitment to take in 20,000 people fleeing Afghanistan, we look at the psychological impacts of trying to start again in a new country. Anand Jagatia speaks to Afraa, who was forcibly displaced fro
PLUS. Det Europæiske Miljøagentur, EEA, melder i en ny rapport om et europæisk vandmiljø, der over en bred kam er under pres. Også i Danmark, hvor det bliver mere end svært at leve op til EU's vandrammedirektiv i 2027, vurderer eksperter, mens landbrugsforhandlingerne på Christiansborg går ind i sin af…
As long-time readers of this blog know, we've spilled more than a few pixels on the work of Donald Morisky. His Morisky Medication Adherence Scale (MMAS) has been a financial boon to himself — and the bane of many researchers who have been forced to either retract papers or pay Morisky what they consider to … Continue reading
